Google Tests Screen Sharing and Custom Agents in Antigravity IDE
Summary
- • Google's Antigravity IDE adds experimental Screen Recording to Agent Mode for developer-supplied visual context
- • Custom Agents and Plugins feature surfaces behind a flag, enabling team-defined agent workflows and scripts
- • Plugin format borrows from Anthropic's Claude Code standard, hinting at cross-ecosystem compatibility
- • Both features in experimental state; flagged status suggests rollout is nearer than prototyping
Details
Screen Recording brings developer-supplied visual context into Agent Mode
Developers can stream their screen to Antigravity's agent, enabling observation of emulators, external runtimes, and live bugs outside the editor. Shifts from agent-generated screenshots to developer-supplied input. Mirrors AI Studio's Gemini real-time screen sharing. Primary use cases: mobile/desktop emulator workflows and live bug walkthroughs.
Custom Agents and Plugins unlocks team-defined agent personalities and workflows
Users drop Agent Scripts into an Agents directory and plugins into a Gemini config folder. Teams can define multiple agent workflows and invoke them on demand — going beyond the current Rules and Workflows model that has been a recurring pain point for developers migrating from VS Code and Copilot.
Plugin format aligns with Anthropic's Claude Code standard
Antigravity's plugin format borrows heavily from the standard Anthropic established for Claude Code, hinting at cross-ecosystem compatibility. Plugin authors targeting both platforms would face lower porting costs, potentially accelerating shared tooling ecosystem development across the two leading agentic IDEs.
Antigravity has lagged competitors on customization despite strong positioning
Launched November 2025 alongside Gemini 3 as 'mission control for parallel agents.' Customization surface and external visibility have lagged VS Code + Copilot and Claude Code — these two features address both gaps simultaneously.
Flagged state suggests near-term rollout rather than early prototyping
No public timeline announced, but the flagged state in recent builds suggests Google is in late-stage testing. Release could arrive without much advance notice.
Product Launch = new capability in testing; Tech Info = implementation/compatibility detail; Context = IDE background; Industry Update = release status signal
What This Means
If these features ship, Antigravity closes two of its most cited competitive gaps — limited external visibility and shallow customization — while plugin format alignment with Claude Code could catalyze a shared tooling ecosystem across the two leading agentic IDEs. Developers evaluating agent-first IDEs should monitor whether the plugin standard convergence holds, as it would meaningfully reduce vendor lock-in risk.
